Abstract

A complex cutting-blade tool wherein a neck (14) having a smaller diameter than the diameter of the drill (1) thereof is connected to a shank (13). At the place where the drill and the neck are connected is provided a burr removal cutting blade (115) inclined roughly 45° from the tool center axis. A hole entrance beveling cutting blade (113) is also mounted through fixture to the neck, inclined at an angle of roughly 45° from the tool turning center axis, in a direction opposite to the burr removal cutting blade (115). The fixture can be secured at any position along the length of the neck, wherefore the distance (T) between the burr removal cutting blade and the hole entrance cutting blade can be suitably adjusted so as to correspond to the depth of the machined hole (i.e. the thickness of the workpiece).
